RomoCoat ZINC RICH EPOXY PRIMER-1265
RomaCoat Zinc Rich Epoxy Primer 1265 is a two‑pack metallic zinc‑rich epoxy primer designed as a high‑performance first coat for aggressive, highly corrosive environments.
What this primer is
- Two‑component epoxy primer with metallic zinc dust as the main pigment, giving strong cathodic (sacrificial) protection to steel.
- Used as the first coat in heavy‑duty anti‑corrosive systems for new construction and maintenance.
Where it is typically used
- Offshore and marine: jackets, platforms, jetties, splash zone steel and coastal structures.
- Petrochemical and oil & gas: process structures, pipe racks, tank externals, refineries and terminals.
- Bridges and infrastructure: highway and railway bridges, flyovers and exposed structural steel.
- Power plants and heavy industry: boiler structures, chimneys, conveyors, cranes and general plant steelwork.

Key surface preparation & application notes
- Zinc‑rich coatings are porous; to reduce pinholes in the next coat, first apply a light mist coat, allow air to escape, then apply a full coat.
- If left exposed too long without topcoat, white rust (zinc corrosion products) will form and must be removed before overcoating.
- Steel must be dry, clean and abrasive‑blasted (typically Sa 2 for radiators, Sa 2½ for tanks); old coatings must be roughened sufficiently before applying this primer.
Health, safety and storage (short)
- Avoid inhalation of solvent vapour/paint mist and contact with skin/eyes; ensure forced ventilation in confined or stagnant areas and use PPE as per local regulations.
- Store in a cool, dry, well‑ventilated place; keep containers tightly closed and protected from direct sunlight and heat.
